Sensata Cynergy3 OLS7 Series Optical Sensor Level Switch, Transistor Output, Chassis Mount, Polysulfone Body

This optical level sensor from Sensata Cynergy3 accurately detects the absence or presence of liquid. It's designed for single-point liquid measurement and chassis mounts externally onto a tank for ease of installation.
The sensor is reliable as it resists false triggering caused by foam on the surface of a liquid. This significantly reduces the chances of it giving you an incorrect alarm. It uses an infrared emitter and detector for precise level detection. A switch like this one is commonly used in small-scale installations such as vending machines.

• Maximum pressure of 7 bar for use in high-pressure systems
• Impact and chemical-resistant polysulfone body for durability
• Wide operating temperature range of -25°C to +80°C for use in demanding environments

You can clean this optical sensor with an alcohol-based solvent. Chlorinated solvents may damage the device's housing and are therefore not recommended.

This versatile, general-use sensor can measure any liquid medium that's compatible with polysulfone, including most acids and alkalis.
